In this talk, I will present a series of concrete situations where children make, very intuitively, connections between the past, the present and the future of media. In their play, children often “imagine” future media applications by actually applying them. Their imagination is therefore more than just a fantasy or mental fabrication; it is instead a practice or “form of activity” (Tätigkeit), to use Siegfried Zielinski’s definition of media archaeology. Especially in their act of “repurposing” media and other devices, children become true media archaeologists. In other words, I will offer some thoughts about the child’s play as a media-archaeological laboratory. For this purpose, I will also take into account some general theories about play, game, object lesson, optical toys and language.
